Tongli

What is HT5?

HT5, or Tongli, is a point on the little-finger side of the inner forearm, about one thumb-width above the wrist crease.

It belongs to the Heart channel. In classical Chinese medicine it is the luo-connecting point of that channel, meaning it was described as a junction linking the Heart channel to the Small Intestine channel. Points with that role are taught in every acupuncture curriculum, so HT5 is a well-known point rather than an obscure one.

Tradition gave it a narrow and rather distinctive job list: sudden loss of voice, a tongue that feels stiff or will not form words, palpitations, and a vague heaviness of mood. Later texts added wrist and forearm pain and heavy menstrual bleeding.

Here is the honest verdict. Long traditional standing is not evidence that a point does anything, and it is also not evidence that pressing it is safe for you. Both of those are true, and neither is a reason to ignore the point; they are just reasons not to overstate it.

For HT5 specifically, there is very little useful human research. A handful of small, unblinded Chinese studies have needled HT5 as part of a group of points for speech loss after stroke. That is a long way from showing that your thumb on your own forearm changes anything. The honest summary is: pleasant, low-risk self-massage with a strong traditional pedigree and almost no modern evidence behind it.

One anatomical note matters more here than at most points. The ulnar nerve and ulnar artery run close to this spot on their way into the hand. That is why the instructions below ask for gentle pressure and tell you to stop if you feel tingling or an electric buzz down into your little finger.

Use HT5 as comfort and routine, not as treatment. Anything involving your heartbeat, your speech or unexplained bleeding belongs with a doctor first.

Where is HT5 and how do you find it?

HT5 sits on the palm side of the forearm, on the thumb side of the big tendon at the little-finger edge of your wrist, one thumb-width above the wrist crease.

• Turn your palm up. Rest your forearm on a table with the palm facing the ceiling and the wrist relaxed. Work on the arm that is comfortable; the point exists on both sides.
• Find the pea-shaped bone. At the base of the palm, on the little-finger side, you can feel a small hard pea of bone called the pisiform. It is the main landmark for this corner of the wrist.
• Find the tendon. Bend your wrist towards the little-finger side against your other hand. A strong cord stands up just in front of that pea of bone. That is the flexor carpi ulnaris tendon.
• Locate the wrist crease. Use the deepest crease where the hand meets the forearm, in line with the pisiform bone. This is your starting line.
• Measure one thumb-width up. Move about one thumb-width, roughly 2 cm, up the forearm from that crease, towards the elbow. In traditional terms that is 1 cun.
• Slide just off the tendon. HT5 lies in the small soft hollow on the thumb side of the tendon, not on top of it. Press lightly and you should feel a slight ache or fullness rather than hard cord.

Two near neighbours cause confusion. HT7 sits right at the wrist crease itself, and HT6 sits about half a thumb-width up. HT5 is the one at a full thumb-width. If you are unsure, stay in the soft hollow beside the tendon at that height and accept that you are close enough for self-massage.

Sources agree on this location and the WHO standard description matches it. This is finger pressure only; no needle, no instrument and no skin-breaking of any kind belongs here.

How do you apply pressure to HT5?

1. Settle the arm. Rest your forearm palm-up on a table or on your lap. A supported arm lets you feel the tendon and hollow clearly instead of fighting your own muscle tension.
2. Use the pad of a thumb. Place the flat pad of your opposite thumb in the hollow beside the tendon. Avoid fingernails, knuckles and any hard tool; this is a thin, nerve-rich part of the arm.
3. Press in gently. Aim for a firm but comfortable sensation, around three or four out of ten. A dull ache or mild fullness is the target. Sharp pain means you are pressing too hard or sitting on the tendon.
4. Hold or circle. Either hold steady pressure for 30 to 60 seconds, or make slow small circles for the same time. Breathe normally and do not hold your breath.
5. Swap sides. Repeat on the other forearm so both arms get the same attention. Most people find one side more tender than the other, which is normal.
6. Repeat sensibly. Two or three short sessions a day is plenty. More time does not buy more effect, and long heavy pressing just bruises the area.

Stop straight away if you feel tingling, numbness, burning or an electric buzz running into your ring or little finger. That is nerve irritation, not a sign the point is working. Ease off, shake the hand out and leave the area alone for the rest of the day.

Also stop if the skin reddens and stays sore, if a bruise forms, or if pressing makes any existing wrist pain worse. Keep sessions short on thin or fragile skin, and keep nails trimmed.

Never break the skin, never use heat strong enough to burn, and never press a point instead of taking a medical symptom seriously.

What is HT5 traditionally used for?

• Speech and tongue problems. This is the headline classical claim: sudden loss of voice and a tongue that feels stiff or clumsy. A few small, unblinded Chinese trials have needled HT5 within a larger group of points for aphasia after stroke, alongside speech therapy. Those studies cannot tell us what finger pressure alone does.
• Palpitations and an uneven heartbeat. As the luo-connecting point of the Heart channel, HT5 was used for a heart that feels fluttery or racing. Human evidence here is thin and poor quality. Palpitations need a medical assessment, not a self-massage plan.
• Anxiety and restlessness. Heart channel points were broadly linked to calming the mind. What research exists on acupressure for anxiety mostly used other points, and the trials are small, short and unblinded. Any calming you feel may come from sitting still and breathing slowly, which is still worth something.
• Trouble getting to sleep. Tradition groups HT5 with its neighbours for disturbed sleep. The sleep acupressure literature is weak and dominated by other points. Treat this as a bedtime ritual, not a sleep treatment.
• Wrist and forearm aching. HT5 sits in the muscle and tendon layer of the forearm, so it is also used as a local point for aching after typing, gripping or carrying. Gentle massage of a tired forearm plausibly helps in a simple, non-mysterious way.
• Heavy menstrual bleeding. Some classical texts list HT5 for excessive uterine bleeding. There is no human evidence supporting this at all. Unexplained or heavy bleeding needs a doctor, and pressing a point should never delay that.

Across the whole list, the pattern is the same: a long and specific tradition, and almost no modern testing of self-applied pressure. Expect mild, short-lived, pleasant sensations rather than a change in any diagnosed condition.

Are there tips for using HT5 effectively?

• Find the tendon first, every time. The tendon is the only reliable landmark in this part of the wrist. Locate it, then slide to the soft hollow on its thumb side. Guessing from the skin surface alone usually lands you on bone or cord.
• Less pressure than you think. This is a thin, nerve-rich strip of forearm. Moderate pressure gives you everything gentle pressure gives, plus the bruise. Three or four out of ten is the whole range you need.
• Use both arms. Working each side for the same length of time makes the routine feel balanced and takes under three minutes in total.
• Anchor it to a habit. Pair the routine with something you already do daily, such as sitting down after work or winding down before bed. Consistency is the only part of self-massage you fully control.
• Breathe slowly while you press. Long, unhurried breaths do more for a racing feeling or jittery mood than the thumb does. Use the point as the cue to slow down.
• Pair it with a forearm stretch. If your reason is aching from typing or gripping, follow the pressure with a gentle wrist extension stretch. That addresses the overworked muscles the point sits on.
• Keep a simple note. Jot down what you tried and how you felt afterwards for a couple of weeks. It is the quickest way to spot whether this is doing anything for you personally.
• Warm the arm first. A warm flannel or just rubbing the forearm makes the tissue more comfortable to work on, especially in cold weather.
• Keep it short. Thirty to sixty seconds per side is the sensible dose. Ten minutes of grinding on one spot causes soreness, not benefit.

What do people get wrong with HT5?

• Expecting a cure. The single biggest error. HT5 will not resolve an arrhythmia, reverse aphasia or stop heavy bleeding. Anyone promising that is selling something.
• Pressing on the tendon. Landing on the hard cord instead of the soft hollow beside it. You feel firm resistance rather than a dull ache, and you get nothing but a sore tendon.
• Confusing it with HT7. HT7 sits right at the wrist crease, HT5 a full thumb-width above it. Videos often blur the two. Measure from the crease each time.
• Pushing through tingling. Treating pins and needles in the little finger as proof the point is active. It is nerve irritation. Stop and move on.
• Using a hard tool. Pens, massage sticks and knuckles concentrate force on a thin, nerve-rich area. The thumb pad is the right tool.
• Going too hard for too long. Several minutes of heavy pressure leaves bruising and tenderness that lasts days. Short and gentle beats long and forceful.
• Ignoring chest symptoms. Reaching for a Heart channel point when the real issue is chest pain, breathlessness or fainting. Those need emergency care immediately, not massage.
• Trying to needle it at home. Some readers see trial descriptions and assume they should copy the method. Nothing on this page is a needling instruction. Keep to finger pressure on intact skin.
• Quitting after one go. If you want to know whether it helps your forearm ache or your bedtime routine, give it a couple of weeks of short sessions before deciding.

What does the research on HT5 actually say?

There is very little research on HT5 on its own, and essentially none on self-applied finger pressure at this point.

The main body of work comes from China, where HT5 has been needled as one point in a larger prescription for aphasia, meaning loss of speech, after stroke. These studies are typically small, not blinded, compare against varying standard care, and combine acupuncture with speech and language therapy. That design cannot separate the contribution of HT5 from the rest of the protocol, from the therapy, or from natural recovery in the months after a stroke.

A similar picture applies to the traditional heart-related claims. Reviews of acupuncture for palpitations and arrhythmia describe a small, methodologically weak literature with mixed results, and they do not isolate HT5. No good trial has tested HT5 alone for anxiety, insomnia or menstrual bleeding.

It is worth noting what a strong case looks like for comparison. PC6 on the inner forearm has repeatedly been tested for nausea and vomiting in randomised controlled trials, including trials of pressure bands rather than needles, and it has real supportive evidence for that narrow use. HT5 has nothing resembling that body of work.

So the honest statement is this: no useful human research was found on pressing HT5 with a finger for any condition. That does not mean it has been tested and failed. It means it has not been properly tested at all.

What it means for you is practical. Treat HT5 as a low-risk comfort routine with a long traditional history. Judge it only by how you feel over a couple of weeks. Do not let it stand in for a diagnosis, a medication or a rehabilitation programme, and keep your doctor informed about anything involving your heart, your speech or unexplained bleeding.
